Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since 1947.

Marker horizons are stratigraphic units of the same age and of such distinctive composition and appearance, that despite their presence dating different geographic types, there is dating about their age-equivalence. Fossil faunal and floral assemblages, both marine and terrestrial, make for distinctive marker horizons.

Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils. Body fossils show us what a plant or animal looked like. The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves.

Fossils. What is a fossil and why do we study fossils? This section explains the different methods of fossil preservation and links to a set of detailed pages that describe 14 of the most common fossil types, including ammonites, belemnites, bivalves and trilobites.

There are different types of fossils because remains can be preserved in a variety of ways. Trace fossils. Trace fossils are the preserved evidence of an animal’s activity or behaviour, rather than the remains of the animal itself. Examples of trace fossils that have been found include: trilobite tracks; marine invertebrate burrows.

Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

II. Relative Dating If geological strata (layers) are undisturbed, deeper ones should be older and so strata at a locality can be ranked in age relative to each other. If fossils from one layer resemble fossils from another locality, the two localities can be roughly correlated with each other: Diagnostic fossil (pig teeth are good ones in Africa).

Dating, in geology, determining a chronology or calendar of events in the history of Earth, using to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments.To date past events, processes, formations, and fossil organisms, geologists employ a variety of techniques.

Fossils can be sorted, or classified, into different types, depending on how they formed. Many fossils are of shells, bones, or teeth that have been turned to stone by a process called petrification. There are other types of fossil too.
